Great dog toy
Size: 8 Inch, Color: Pink
The amount of stupid and cute these dogs look like when they shake this ball and smack their own faces! It took a hot second for either dog to understand where to bite on the ball, but now that they do, they both will play with it for a while. Great purchase, came with a pump to blow the ball up.

Love these! They are good quality and my dogs love them so much actually I ordered a second set for my sister's dogs and they love them as well! Great buy for the price! I'm sure I will be buying some more but thankfully it isn't one week later because they are sturdy!

Heavy chewers can't break these alone.
Style: 5 Pcs No Stuffing Basic
These toys are AWESOME! As long as you don't get tricked into playing tug of war with them, they will last a very long time (almost 2 months) with a heavy chewer that tears through most toys in a couple hours. The tug pressure rips a seam. Then, that portion is a goner. However, the rest of the toy stays intact.

Well made & my dog LOVES them!
Style: 5 Pcs No Stuffing Basic
Great value for FIVE very cute and well made stuff-less toys with crinkly paper inside and TWO squeakers each. My dog loves playing with them! I have two in his toy box and put three up to save for later for backup if/when he destroys the first two. 😂 I love the cute and unique designs of the squirrel, donkey, fox, cow, and giraffe, too.
